Linearly weighted average, newest observation carrying weight period.
Valid scalar defaults sum weighted terms oldest first and omit nonfinite
results. Supplied skip weights period
finite observations and holds across gaps; propagate requires a full
chronological window. Warmup is NaN. The option path validates a positive
safe-integer period and a missing policy, throwing RangeError or TypeError.
